func (PrivKey) PubKey 

func (privKey PrivKey) PubKey() cryptotypes.PubKey

PubKey returns the ECDSA private key's public key. If the privkey is not valid it returns a nil value.

func (*PrivKey) Reset 

func (m *PrivKey) Reset()

func (PrivKey) Sign 

func (privKey PrivKey) Sign(digestBz []byte) ([]byte, error)

Sign creates a recoverable ECDSA signature on the secp256k1 curve over the provided hash of the message. The produced signature is 65 bytes where the last byte contains the recovery ID.

func (*PrivKey) Size 

func (m *PrivKey) Size() (n int)

func (*PrivKey) String 

func (m *PrivKey) String() string

func (PrivKey) ToECDSA 

func (privKey PrivKey) ToECDSA() (*ecdsa.PrivateKey, error)

ToECDSA returns the ECDSA private key as a reference to ecdsa.PrivateKey type.

type PubKey 

type PubKey struct {
	Key []byte `protobuf:"bytes,1,opt,name=key,proto3" json:"key,omitempty"`
}

PubKey defines a type alias for an ecdsa.PublicKey that implements Tendermint's PubKey interface. It represents the 33-byte compressed public key format.

func (PubKey) Address 

func (pubKey PubKey) Address() tmcrypto.Address

Address returns the address of the ECDSA public key. The function will return an empty address if the public key is invalid.

func (PubKey) Bytes 

func (pubKey PubKey) Bytes() []byte

Bytes returns the raw bytes of the ECDSA public key.

func (*PubKey) Descriptor 

func (*PubKey) Descriptor() ([]byte, []int)

func (PubKey) Equals 

func (pubKey PubKey) Equals(other cryptotypes.PubKey) bool

Equals returns true if the pubkey type is the same and their bytes are deeply equal.
